How expensive is it to implement 3D printing?

This mainly depends on the type of 3D printing technology used. 3D printers span the cost spectrum from relatively cheap machines, suitable for an office environment, to large, expensive, industrial printers. Within a given technology category, the difference between low-end and high-end systems often includes the size of the parts, the variety and quality of the materials, the accuracy, reliability and consistency of the systems.

Compared to traditional prototype modeling or traditional manufacturing methods such as CNC machining or injection molding, 3D printing is typically much faster and much less expensive. As the benefits and applications increase, the technology can be scaled appropriately.
